在angular 2中使用正则表达式时出错，模块解析失败：严格模式下的八进制文字

Question

嗨，我的environment.ts文件中有一个正则表达式

export const environment = {

passwordPolicy: "^(?!.*(.)\1\1)(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}.*$"

};

但是当我进行ng测试时出现以下错误

ERROR in ./src/environments/environment.ts
Module parse failed: Octal literal in strict mode (74:30)
You may need an appropriate loader to handle this file type.
|     passwordPolicy: "^(?!.*(.)\1\1)(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}.*$"
| };

请帮助我 谢谢
